amateur runner/triathlete here:

- i do agree that this is not a real problem. i do exactly as you say, i check my soles every now and then, and if i see any deterioration, the shoes go straight to the bin. i wouldn't be a user of this product, having said that;

- your idea of "email (me) every X months with a 20% of coupon for the SAME PAIR" i think is a great idea. i tend to buy 2/3 pairs of the same running shoe every time. if instead i could establish a rule that after x distance i get sent a new pair that would be another thing off my to-do list. there is definitely a subscription model here somewhere.
